ATTACHMENT FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Patented Aug. 14, 191?.

Application filed October 26, 1915. Serial No. 57,932.

To all whom it may concern Be it known that I, HUeHPorrs, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Attachments for Internal- Combustion Engines, of which the following is a specification.

This invention relates to new and useful improvements in an attachment for internal combustion engines.

The object of the invention is to provide a device of the character described wheretake pipe and thence to the cylinders.

Another object of the invention resides in the provision of means whereby the amount of moisture so delivered may be controlled or the supply entirely cut 05.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings wherein:

Figure l is a side elevation of an internal combustion engine with the attachment applied thereto,

Figs. 2 and 3 show front and sideelevations respectively of the working barrel employed with the plunger therein,

Figs. 4 and 5 show views of said plunger taken at right angles to each other,

Fig. 6 shows a fragmentary longitudinal sectional view of the plunger,

Fig. 7 shows a plan view of the arm employed,

Figs. 8 and 9 show detailed views of the manual lever for controlling the device, and Fig. 10 shows a fragmentary vertical sectional view of the lower endv of the barrel.

Referring now more particularly to the drawings wherein like numerals of reference designate similar parts in each of the figures the numeral 1 refers to the engine, having the usual cylinders 2 and the intake pipe 3 leading from the carburetei; 4 to said cylinders. The numeral 5 refers to the radiator, connected with which is the water pipe 6 through which the water circulates from the radiator into the usual jackets (not Shown) around said cylinders. Fixed to the front board 7 of the body of the ordidown in the barrel.

nary automobile, to which the device is shown applied, is the working barrel 8 having the hollow plunger 9 reciprocating therein. Two pipes 10 and 11 communicate with this barrel, the former being tapped through the water pipe 6 and its free end extending on through said pipe and projecting above the water level in the radiator and the latter communicating also with the water pipe 12. Leading also from the lowerend of the barrel 8 and communicatmg with the intake pipe 3 is the conduit 13. The plunger 9 normally bloc-ks both pipes 10 and 11. Rotatable in the bearings 1 1 and 15 is the shaft 16 which extends through the front board 7. One end of this shaft has the hand lever 17 fixed thereon and fixed to the other end thereof is the arm 18 whose free end has a pivotal connection with the upper end of the plunger 9. It is obvious that by a manipulation of the lever 17 the plunger may be moved up and Through the wall of thls plunger is the orifice 19 and when the same is moved into registration with the end of the pipe 10 the vapor from the radiator will be drawn by suction through the pipes 10 and 13 into the intake pipe and thence to the cylinders. In case it is desired I to discharge water into the intake pipe the plunger 9 may be moved farther until the orifice 19 registers with the end of the pipe 1'1 and the water will be drawn from the water pipe 12 through the pipes 11 and 13 v and discharged into the intake pipe. A smaller orifice 20 is provided through the wall of the plunger which may be, in the manner hereinbefore described, brought into alinement with the pipe 10 or 11 and a smaller amount of vapor or water as the case may be will thus be admitted to the intake pipe. Any well known mechanism may be provided for securing the lever 17 in any desired fixed position so as to completely block the pipes 10 and 11 or to bring either of them into communication with the pipe 13 through either of the orifices 19 or ..O.

The lower end of the barrel 8 is controlled by a ball check valve 21 which is lifted bv the suction from the cylinders against the seat 22 when the device is in operation so as to close said seat and prevent the admission of air therethrough, but when the plunger 9 is moved to block the pipes 10 and 11 the suction will be cut off and the valve 21 will This device is providedfor the purpose of supplying moisture to the cylinders as it has been found by practice that a certain amount of moisture mingled with the fuel conduces to a more perfect combustion and also prevents the formation of carbon in the cylinders.

What I claim is 2- 1. An attachment for internal combustion engines including a barrel, a pipe communicating therewith, the free end of which projects into the radiator of the engine, a hollow plunger in said barrel provided to block and unblock said pipe and a conduit communicating, through the plunger, with said pipe and leading from the barrel to the engine intake pipe.

2. An internal combustion engine attachment including a barrel a pair of pipes communicating therewith at one end and Whose other ends project above the water level in the radiator and communicate with the water chamber of the engine respectively, a hollow plunger in said barrel provided with an orifice through the wall thereof and ar I ranged to normally block said pipes, a con duit leading from said barrel to the engine intake and means for manipulating said plunger, so as to register said orifices alternatively with said pipes and bring them into communication alternatively with said conduit, through said plunger.

3, An internal combustion engine attachment including a barrel a pair of pipes communlcaltlng atone end with said barrel and, whose other ends termlnate 1n the water chamber of the engine above and below the water level thereof respectively, a hollow plunger in said barrel provided with an orifice through the wall thereof normall blocking the adjacent ends of said pipes, a conduit leading from said barrel into the engine intake and means for manipulating the plunger to register said orifice altera plurality of vertically alined orifices of unequal capacity through the plunger wall, a conduit leading from said barrel into the engine intake and means for manipulating the plunger to bring either of said orifices into registration alternatively with said pipes whereby the pipes are brought into communication alternatively with the conduit, through said hollow plunger.

5. An internal combustion engine attachment including a pair of pipes, one end of one of which terminates in the water chamber of the engine above the water level and one end of the other of which terminates in said chamber below the water level, a conduit communicating'with the engine intake at one end and a mechanism whereby the other ends of said pipes may be brought into communication with said conduit alternatively.

In testimony whereof I have. signed my name to this specification in the presence of two subscribing witnesses. f i
